Blast in Nigeria venue showing World Cup leaves 13 dead

An explosion at a venue in Nigeria which was showing World Cup football has left at least 13 people dead, according to Reuters. Around 20 people were left severely injured in what police reportedly called an "attack".

A number of pick-up trucks carrying bodies arrived at a hospital in northeast Nigeria, a hospital source said after an explosion ripped through a venue in the town of Damaturu where fans had gathered to watch a World Cup match.

It was not immediately clear how many people had been injured or if anyone had been killed. A police official confirmed that there had been an "attack," but he declined togive further details.
